The Honoré Mercier Bridge in Quebec, Canada, connects the Montreal borough of LaSalle on the Island of Montreal with the Mohawk reserve of Kahnawake and the suburb of Châteauguay on the south shore of the Saint Lawrence River. It is the most direct southerly route from the island of Montreal toward the US border. It carries Route 138, originally Route 4. It is in length and contains four steel trusses on its first section. The height of the bridge varies from to with the highest sections located over the St. Lawrence Seaway. The bridge is named after former premier of Quebec Honoré Mercier. The bridge has two lanes of traffic in each direction and a total span of nearly two kilometres. At its highest point, the bridge rises 36 metres above the river. There is a narrow sidewalk on the side headed to Châteauguay that was for use by foot or bicycle, however it hasn't been open since major repairs began in 2009. The roadway has been characterized by numerous repairs. An estimated 30 million vehicles use the bridge every year.〔 ==History== Before the bridge was built there was a ferry service. The bridge, known in project as "Saint-Louis bridge" (for nearby located Lake Saint-Louis and the parish of Saint-Louis-de-Caughnawaga, today part of the Kahnawake reserve), was designed by 11 French-Canadian engineers, who were all graduates of the École Polytechnique de Montréal, and was built by the Dominion Bridge Company Ltd under a government-funded work program. Construction of the bridge began in November 1932 and was completed in the early summer of 1934. It was opened to traffic on June 22, 1934 (named "Honoré-Mercier" during its inauguration by mayor Taschereau, 10 months ahead of schedule with a toll of 50 cents for an automobile and driver—later reduced to 25 cents. Today there is no toll charged for crossing the bridge. The original east approach was on Lafleur Avenue, which ran straight into the Gauron Bridge over the Lachine Canal. The higher section over the Saint Lawrence Seaway was added in the late 1950s. In August 1963, the Quebec Department of Public Works approved the construction of a "second" bridge downstream from the first. This increased the number of lanes from two to four. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Honoré Mercier Bridge」の詳細全文を読む スポンサード リンク
